Definitions

  • the present disclosure relates to systems and methods for aligning prefabricated building modules as they are combined to form a modular building.
  • buildings have been constructed almost entirely on-site, starting with a framework of girders, and then adding floors, walls, outer cladding, and the various internal electrical, plumbing, and electrical connections.
  • Each module is a generally box shaped unit with a primary chassis or framework comprising vertical support posts and horizontal cross members joined together at comer nodes.
  • a prefabricated module may also be at least partially finished with internal walls, flooring, and hookups for electricity and water.
  • an initial tier of modules is installed starting with a first module affixed to a building foundation or platform. Horizontally adjacent modules are then installed in sequence and fixed in place. Subsequent tiers of modules can be installed over installed lower tiers.
  • a significant issue during such a process is the need to align the various modules as they are lowered in place. Where components on one module are designed to interlock with corresponding components on another module, the initial alignment of a module being placed must be within the narrow range of tolerance for such interaction. For safety reasons, construction personnel should stand off some distance from the module as it is being lowered into place. This increases the difficulty of accurate manual module alignment during the building process.
  • a particular situation where accurate installation tolerance must be met is where a builder wants to use modules with facade panels pre-installed on the module. Facade panels on adjacent modules can be configured to interlock as one module is lowered into place next to an already positioned module. For adjacent panels to interlock and seal during module installation, an alignment tolerance for panel interlock, and therefore alignment tolerance for the module, of less than or equal to 10mm can be required.
  • alignment structures comprising various female guides and male guides mounted on the edges of one or more of the interior facing sides of the module chassis.
  • Alignment structures on a new module to be installed interact with alignment structures on an adjacent previously installed module to automatically align the new module relative to the position of the prior module as the new module is lowered into position.
  • the methods and systems provide for alignment of module edges within a range of tolerances sufficiently narrow that prefabricated modules with pre-installed fagade panels designed to interlock with adjacent panels can be used.
  • Initial engagement of the alignment structures can be achieved when the new module is positioned over an adjacent prior installed module with only a moderate degree of accuracy.
  • the alignment structures are configured to most tightly constrain horizontal motion of an outer edge of the new module relative to an adjacent outer edge of an installed module.
  • Automatic alignment can be within several millimeters, such as +/4 mm from an ideal position. This is sufficiently accurate to be within the alignment tolerances required for interlocking fagade panels to engage (and whereon final relevant adjustment of fagade panel positions can be accomplished according to the panel design, and may be automatic in accordance with interlock hardware of the panels themselves.
  • the position of one or more additional edges of the new module are also constrained by the alignment structures as the new module is lowered into place but to a somewhat lesser degree along at least one horizontal axis to compensate for variations in the positions of alignment components on the new module relevant to each other and to mating components of a prior module within design tolerances and avoid binding or damage to components during the installation process.
  • the alignment structures can be configured and positioned so that they automatically engage and disengage at different heights as a new module is lowered into place.
  • the alignment structures are configured to entirely disengage so that the present structures and methods can be used in conjunction with conventional hardware for providing final object alignment, such as tapered alignment pins mounted on and extending upwards from the substrate and that engage alignment holes in the underside of a module when the module is very close to the substrate on which it is being placed, such as within a few centimeters.
  • the present systems and methods operate to accurately and automatically align a new module to the degree required for engagement of the alignment pins.
  • the present alignment structures automatically disengage and the alignment pins operate to finalize the placement of the module as it is lowered into its final position.
  • the degree to which a module edge is constrained during installation can vary as the module is lowered and as alignment structures that constrain other edges of the module are automatically engaged or disengaged.
  • alignment hardware operates to tightly constrain a first edge of a new module as it is initially lowered through a first installation zone while a second edge is constrained more loosely.
  • the alignment structures constraining the first edge transition from tight constraint to a looser constraint
  • the alignment structures constraining the second edge disengage and alignment structures to constrain the position of a third edge automatically engage and operate to tightly constrain the position of the third edge.
  • only two edges of the module are constrained by the alignment structures with one edge tightly constrained and the other edge more loosely constrained.
  • a limited set of alignment structure types is provided and which are combined to provide the alignment structures for placement of new modules in a variety of situations, including placement of a first module, of a standard module along a row of modules, of a module at the start of a second row of modules, and of a final module in the second row of modules.
  • the alignment structures comprise first, second, and third types of male guides and first, second, and third types of female guides.
  • First type male and first type female guides are compatible and configured so that when a first type male guide is engaged in a first type female guide and can slide along the guide axis, motion of the male guide is narrowly constrained both along a lateral axis running across the channel of the female guide perpendicular to the guide axis and along a normal axis that is perpendicular to the guide axis and the lateral axis and so extends outwards away from the channel of the female guide.
  • motion along the lateral axis and along the normal axis is constrained to a first constraint amount, although amount of constraint need not be the same for both axes.
  • the first constraint amount reflects the maximum horizontal displacement permitted for the edge of a module being installed that has the most stringent position requirements, such as the outer edge of a new module that will be adjacent an outer edge of a placed module, and where, for example, facade panels are pre-installed and very close alignment of adjacent facade edges is required during module installation.
  • the first male and female guide types are configured so that when type one male and female guides are engaged, the male guide cannot be disengaged from the female guide except by motion of the male guide relative to the female guide along the guide axis.
  • the first male and female guide types are in a dovetail configuration with side angle of between 40 and 50 degrees, such as 45 degrees and the first constraint amount is between about 3mm and 5mm, such as about 4mm.
  • Second type male and second type female guides are compatible with each other and configured so that when a second type male guide is engaged within a second type female guide, motion of the male guide along the lateral axis is constrained to a second constraint amount that is larger than the first constraint amount.
  • the permitted range of motion of the male guide along the lateral axis is larger for a second type male guide in a second type female guide than the lateral axis range of motion permitted for a first type male guide type in a first type female guide.
  • the constraint amount in the lateral axis for engaged male and female guides of the second type can be the same or larger than the amount provided by engaged male and female guides of the first type.
  • the lateral axis constraint amount is substantially the same for first type and second type guides.
  • the second male and female guide types are configured so that when second type male and female guides are engaged, the male guide cannot be disengaged from the female guide except by motion along the guide axis.
  • the second male and female guide types are in a dovetail configuration with side angle of between 20 and 40 degrees, such as 30 degrees and the second constraint amount on the lateral axis is between about 8mm and 12mm, such as about 10mm while the second constraint amount along the normal axis is substantially the same as the first constraint amount.
  • Third type male and third type female guides are compatible with each other and configured so that when a third type male guide is engaged within a third type female guide, motion of the male guide along the lateral axis is constrained to a third constraint amount that is larger than the first constraint amount and, for example, may equal the second lateral axis constraint amount.
  • the third guide types are configured so that when a third type male guide is engaged within a third type female guide, the male guide can be disengaged from the female guide by moving the male guide away from the female guide channel along the normal axis. Motion of the male guide along the normal axis and into the female guide is constrained by the physical components themselves.
  • a third constraint along the normal axis can be defined as a range of motion along the normal axis within which the male guide will remain at least partially within and constrained in the lateral axis by the female guide.
  • the third type male guide has a rectangular cross-section and the third type female guide has a rectangular cross-section channel and the third constraint amount on both the lateral axis and the normal axis is substantially equal to the second lateral axis constraint amount , such as between about 8mm and 12mm, such as about 10mm.
  • first, second, and third male and female guides are positioned on the exterior of a module and with consideration of corresponding female and male guides present on an adjacent wall of a similar or different module design depending on the place module in the installation process (e.g., a first module, typical row module, second row start module, or second row end module.).
  • pilots are mounted on the top of an installed module and placed to interact with alignment structure on a new module. As the new module is lowered, the pilot captures the alignment structure on the new module and positions the new module relative to alignment structure on the placed module before the bottom of the new module is lower than the top of the placed module, and after which the alignment structures on the new and placed module engage.
  • a pilot can be mounted directly to the substrate to provide alignment of a new module edge where there is no adjacent edge of an installed module to reference. After installation of a new module, any pilots used in the process can be removed for reuse in installation of another module.
  • a set of pilots can be provided with different types of male and female guides mounted vertically thereon for use in conjunction with compatible male and female guides.
  • the set of pilots include first and second type male pilots having mounted thereon a respective first type or second type male guide, and first, second, and third type female pilots have mounted thereon, respectively, a first, second, or third type female guide.

  • Module placed in a comer condition adjacent a short side of an already placed chassis such as second row start
  • building modules are provided with a series of female guides and/or male guides on the edges of one or more of the exterior sides of the module chassis.

  • pilot components with male or female guides can be removably mounted on the top of an already placed module, such as to existing hardware in the upper comers of the module, and operate to interact with alignment structure on a new module to position the respective edge of the new module relative to alignment structure on the placed module before the bottom of the new module is lower than the top of the placed module. Pilots can also be mounted to the substrate to provide an alignment structure where alignment of an edge of a new module is desired but where there is no adjacent wall of a placed module to use as an alignment reference. One example of this is placement of the first module. After installation of a module, any pilots used in the process can be removed for reuse in installation of another module.

  • the alignment guides on the module sides are used in conjunction with tapered alignment pins mounted on and extending upwards from the substrate a short distance, such as about 20mm, and that engage alignment holes in the underside of a new module and operate to finalize the accurate placement of the new module on the substrate as the module is lowered this small remaining distance to the substrate.
  • Such alignment pins can take various forms, such as cones, pyramids, tapered cylinders, etc. and various suitable structures are known in the art.

Abstract

L'invention concerne des systèmes et des procédés destinés à être utilisés dans l'alignement automatique de modules de construction préfabriqués. Des structures d'alignement d'accouplement sur un nouveau module et un ou plusieurs modules placés ou pilotes montés interagissent lorsque le nouveau module est abaissé pour aligner les bords du nouveau module par rapport aux éléments placés. Différents types de structure d'alignement sont utilisés pour fournir différents degrés d'alignement de position pour différents bords d'un module au cours de l'installation. Lorsque deux bords d'un module sont simultanément contraints, une position horizontale d'un bord est contrainte à un degré supérieur par rapport à celui du second bord. Des structures d'alignement peuvent également être conçues de sorte que le degré de contrainte de position sur un bord particulier varie et en vue de changer les bords de module qui sont contraints lorsqu'un module est abaissé en position. Le système et les procédés sont appropriés pour être utilisés avec des modules de construction préfabriqués ayant des panneaux de façade à emboîtement pré-installés.
